Quantum field theory describes three of the four fundamental forces of nature, electromagnetism, and the strong and weak ...

That at least is the case with the strong nuclear force, one of four fundamental forces of nature (the others being electromagnetism, gravity and the weak nuclear force). The strong force holds ...

Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity holds stars together and keeps us on the ground. The electromagnetic force ...

These four fundamental forces exist between fermions (quarks and leptons). They arise from the exchange of bosons. Bosons are the 'force carrying' or 'force-mediating' particles. If a fermion ...
